Fixed `to the inner or rear end" olf the broilerdrawer are winged extensions 30 (see 3)y which, respectively, lap by theopen sides ofthe Vvreslgxective inner strips. (See Fig. 11:) Eachwinged-extension v3|lbears a hub `31 'on which turns Va roller 32located to lie between the `flanges 21- -and Z2-of Eeachinner strip.Fixed to the outer or ifo-re end fot the `side f2llof veach of the innerstrips is an extension 34 bearing a hub 35 on which turns 1a roller '3BAengaging the bottom llaites Il ofgtlie broiler drawer. `@See Figs. 5and When the vdrawer Ihas been moved full into the broiler compartment,`as shown 'in Fig. 2, its front panel 3V will ihave bearing aga-inst theIface of the range body and the drawer will be resting `along the foreend port-ions of its 'bot-tom plates 1 di; rec't'lywupon `the rollers 36borne by the `inner strips, land valongV its rear end portions, throng-hthe rollers 132, `upon the bottom fiamges V22, of the inner strips. i Asthe drawer 'is pulled out the inner strips, Vupon which the draw-er isthen resting, will gbe 'telesoopioally withdrawn from the outer strips,the inner strips then riding upon the rollers 23 and the rollers 29borne by the inner strips then running upon the bottom flanges I9 of theouter strips. During this withdrawal the hubs 28 of the rollers 29 willdraw along the slots I6 in the sides l5 of the outer or fixed strips.The telescopic withdrawal of the inner strips, bearing the drawer, willcontinue until the hubs 28 engage the outer ends of the slots I6 whenfurther withdrawal of the drawer by way of telescopic withdrawal of theinner strips is stopped. Withdrawal of the drawer continues by thedraw.- er continuing to run on the rollers 36, borne by the innerstrips, while its rollers 32V will first run upon the bottom flanges 22.of the inner strips and later the overbalancing weight of the drawerwill cause the rollers 32 to engage andrun upon the top anges 2| of theinner strips.' Complete withdrawal of the drawer is prevented by contactof the rollers 32 borne by the broiler drawer with the rollers 36 borneby the inner strips, the inner strips then being held against furtherIwithdrawal. Completewithdrawal of the drawer is also prevented by meanslater to be referred to.

Located within the drawer are sets of arms 38,

38, and 39, 39, respectively. Each set of arms is connected by a plate40. This plate is preferably made of sheet metal and the arms are in thenature of flanges turned from the ends of the plate. Each set of arms ispivoted to the sides of the drawer, the pivotal connections comprising ascrew 4| on the shank of which is arranged a spacing sleeve 42 arrangedbetween the head of the screw and the side of the drawer and upon whichsleeve the arm turns; (See Fig. 9.)' The screwfafter passing through thesleeve and side of the drawer, is secured by a cap nut 43. The arms arepivoted to the sides of the drawer at points adjacentr the bottoms ofits sides so that the arms may be turned to assume a downturned positionor an upturned raised position. The sets of arms are connected to turnin unison by a plate 44 interposed between the top ends of therespective sets of arms. This plate is provided along its sides withupturned flanges 45 by which the top ends of the respective arms 39 lapon the outside (see Fig. 8) and are secured by fastenings which provideboth a pivotal connection between the sets of arms and the plate 44 andbear, also, rollers 46 which extend in part above the respectiveflanges. Each of these rollers turns upon a hub 4l. This hub is providedwith an extension 41 of lesser diameter than the main hub and thisextension fits within an opening formed in the flange-45, afterwhich thehub is secured by a screw 48 passed from the inside through the hub andits extension and through an opening in the end of the arm 38 and thensecured by a nut 49, a lock washer being preferably interposed betweenthe nut and the side 'of the arm.

Resting upon the rol1ers46 is the broiler pan 50 containing a grid 5|.The broiler pan has the Vgeneral form of the top of the drawer butspaced fromv the sides and ends of the drawer to fit loosely therein.Consequently as the sets of arms are raised or lowered the broiler pan,riding upon the rollers 46, willhave a substantially vertical rise andfall within the drawer.

The weight of the broiler pan and grid will normally be suflicient tomaintain the arms in a downturned position.` This is preferablycounteracted, to a certain extent at least, by providing the sets ofarms 38, 33 each with a spring 52 ywhich tends to raise all the arms..These 4 springs are arranged upon the hubs 42 with one end bearingagainst the arms and the other against the drawer, the springs beingtensioned to assist in raising the arms as aforesaid.

The sets of arms bearing the broiler pan are raised into anupturned'position elevating the broiler pan within the broiler drawer orthe arms allowed to ldrop for lowering the broiler pan, as the drawer ismoved in and out,V by a cam 54 which slides upon the bottom 6 of thebroiler drawer.

The general form of this cam is shown in Fig.

v rear end 58. Itis provided along its fore end por'- tion with sets ofrollers 6U borne by its sides 5l.V

These rollers lie interposed between the sides of the cam and theadjacent side, plates 8 of the broiler drawer. Elevation of theserollers is prevented by plates 6 I secured to the plates 'l of thedrawer with lateral extension over the respective rollers. The rollershave extension to have engagement with the bottom of the broiler drawerand roll thereon, thus giving easy slidability to the cam, although therear end portions of its sides may engage the bottom ofthe drawer,trailing thereon. When theV cam isrmoved back inthe broiler drawer itsless elevated rear portion will pass through the opening 9 left belowthe back of the broiler drawer and between it and the bottom of thedrawer, as previously explained. 'Ihe cani may be moved back in thebroiler drawer until its rear set of rollers 60 engages xed'stops 62which are Iixed to the plates 'l of the drawer to lie in theY pathof'the rollers'l At about the same time that the rollers engage thestops the surface of the cam will have engaged the bottom edge of theback of the broiler drawer which also acts as a stop'for limiting therearward movement of the cam. As will presently be explained the cam isheld xed when vits surface engages.

the bottom edge of the back;of the broiler drawer and the cam willprevent any undue withdrawal of thedrawer from `out of the broilercompartment and from the respective stops.

Engaging the .cam surface 55 are rollers 63, each borne by a bracket 64xed to the plate 40 which connects the set of arms 38, 38. The rollersare held in contact with the cam surface to follow its contour by theweight of the broiler pan, grid borneby it, and material being broled.,The arrangement is such that when the rollers 63 are engaging the highsurface of the cam, as shown in Fig. 3, the arms will beraised tosupport the broiler panin its uppermost raised position in the broilerdrawer, and when the rollersare engaging the lowl surface ofthe cam thearms will assume a downturned position, as shown in Fig. 2, where thearms are shown supporting the broiler pan in its lowermost position inthe broiler drawer. Thus thebroiler` pan is raised bythe cam, dependentupon its position in .the broiler drawer and permitting of lowering bygravity, dependent upon the position ofthe cam in the broiler drawer.
